What follows is the full text as it appears on the opening page:

IS THIS TOMORROW is published for the one purpose - TO MAKE YOU THINK! To make you more alert to the menace of Communism.

Today, there are approximately 85,000 official members of the Communist Party in the United States. There are hundreds of additional members whose names are not carried on the Party roles because acting as disciplined fifth columnists of the Kremlin, they have wormed their way into key positions in government offices, trade unions, and other positions of public trust.

Communists themselves claim that for every official Party member, there are ten others ready, willing, and able to do the Party's bidding.

These people are working day and night - laying the groundwork to overthrow YOUR GOVERNMENT!

The average American is prone to say, "It Can't Happen Here." Millions of people in other countries used to say the same thing.

Today, they are dead - or living in Communist slavery. IT MUST NOT HAPPEN HERE!

IS THIS TOMORROW is being distributed as a public service by the CATECHETICAL GUILD Educational Society 145 E. 5th St., St. Paul, 1, Minn.
